` It is therefore' the object of this inventionA toimprove the construction-and relation of -such 4a -sleeve valve and its supporting land actuatiii .devices andcoperating parts soV that it s all operate properly .and Lwith the 'ractical conditions 'and best-results under especiallyso that its free expansion shall not be interfered with, so that neither-the' valve no1' its actuating iiieaiis shall be caused to bind in operation and-so that a large area of ports niay be obtained and in good form for high speed. l l Other improvements and desirable results -Willbe ointed out hereinafter.

The invention will be more fully ex- -pla-ined hereinafter with reference to the ac' companyiiig drawings in which it is illus trated and in wliich-I- Figure 1` is -a partial detail view-in axial section illustrating the relation of the sleeve valve and the valve chamber, the extreme positions of the snp orting and actuating lever being indicated y dotted lines.
